Metrology Glossary: Inductance
What Is Inductance?
Inductance is a fundamental concept in electricity and magnetism that signifies the inherent opposition of an electrical conductor to changes in the flowing current. This resistance arises from the intricate interplay between the conductor, the magnetic field it generates, and the voltage induced in response to changes in the field. Linked to electromagnetic phenomena, inductance is a cornerstone in the understanding of circuits and transformers, influencing their behavior and efficiency. Recognizing inductance is pivotal for engineers and physicists, as it lays the groundwork for comprehending the dynamic relationships between electric currents and magnetic fields within numerous applications in technology and electrical systems.
